Description

Technical Field

[0001] The utility model belongs to the technical field of polishing machines, in particular to an abrasive belt polishing machine. Background Art

[0002] A belt polisher is an electric tool that uses abrasive belt grinding technology to process workpieces. Its working principle is to remove the damaged layer on the surface of the workpiece through a high-speed rotating abrasive belt to achieve the required surface roughness. This process requires precise control of the speed and pressure of the abrasive belt to ensure that the damaged layer is effectively removed without damaging the workpiece structure. Abrasive belts are made of a variety of materials, including silicon carbide, alumina, ceramics, zirconium corundum, etc. Abrasive belts of different materials have different hardness and wear resistance, and are suitable for different processing needs.

[0003] However, there are some problems with the prior art: although the existing belt polishers are increasingly used in production lines to improve production efficiency, in actual use, workers are usually required to hold the workpiece to be polished, so that the workpiece is close to and contacts the high-speed rotating belt for polishing. This method makes the workers' hands close to the belt, which is easy to cause accidental injuries. Therefore, we propose a belt polisher. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 5 As shown, the belt polisher provided by the embodiment of the utility model includes a base 1, a frame 2 is fixedly installed on the base 1, a polishing mechanism is arranged on the frame 2, a slot 3 is opened on the top of the base 1, a square plate 4 is movably installed inside the slot 3, a slide plate 5 is arranged on the square plate 4, fixed blocks 6 are fixedly installed on both sides of the top of the slide plate 5, a brake motor 7 is fixedly installed on the right side of the top of the slide plate 5, a screw rod 8 is fixedly sleeved on the output shaft of the brake motor 7, a splint 9 is threadedly sleeved on the outer surface of the screw rod 8, and a gasket 10 is fixedly installed on the end of the splint 9 away from the brake motor 7.

[0027] Furthermore, the polishing mechanism includes a driving motor 11, which is fixedly installed on the right side of the back side of the frame 2. The output shaft of the driving motor 11 is fixedly sleeved with a driving wheel 12. A first driven wheel 13 is arranged on the left side of the front side of the frame 2. A second driven wheel 14 is rotatably connected to the top of the front side of the frame 2. A sanding belt body 15 is transmission-connected between the driving wheel 12, the first driven wheel 13 and the second driven wheel 14.

[0028] By starting the drive motor 11, the driving wheel 12 can be rotated, so that the sand belt body 15 can be driven along the outer surfaces of the driving wheel 12, the first driven wheel 13 and the second driven wheel 14, and then the workpiece placed on the slide plate 5 can be polished.

[0029] Furthermore, a guide rail 16 is fixedly installed in the middle of the top end of the square plate 4, the slide plate 5 is slidably connected to the guide rail 16, and a driving mechanism is connected between the slide plate 5 and the square plate 4.

[0030] Furthermore, the driving mechanism includes a square rod 17. The square rod 17 is fixedly installed on the left side of the slide plate 5. A through hole 18 is formed in the square rod 17. A servo motor 19 is fixedly installed on the left side of the bottom of the square plate 4. The output shaft of the servo motor 19 is fixedly sleeved with a rotating shaft 20. The top of the rotating shaft 20 extends above the square plate 4 and is fixedly connected to a disc 21. A round block 22 located inside the through hole 18 is fixedly installed on the disc 21.

[0031] By starting the servo motor 19, the rotating shaft 20 can drive the disc 21 and the round block 22 to rotate, so that the round block 22 can drive the slide plate 5 to reciprocate along the surface of the guide rail 16 through the square rod 17. Furthermore, the workpiece on the slide plate 5 can reciprocate under the sand belt body 15, so that the workpiece can be evenly polished.

[0032] Furthermore, a cylinder 23 is fixedly installed in the middle of the bottom end of the base 1, and the telescopic end of the cylinder 23 is fixedly connected to the bottom of the square plate 4.

[0033] By starting the cylinder 23, the square plate 4 can drive the slide plate 5 to move upward, so that workpieces of different heights can all contact the bottom of the sand belt body 15 for polishing work, improving the applicability of the device.

[0034] Furthermore, guide rods 24 are fixedly installed on both sides of the bottom of the square plate 4, and the bottom ends of the guide rods 24 extend to the bottom of the base 1.

[0035] Through the design of the guide rods 24, a good guiding effect can be exerted on the square plate 4, so that the square plate 4 can move more stably up and down.

[0036] Furthermore, a square hole 25 is formed in the left side of the front surface of the frame 2. An electric push rod 26 is fixedly installed on the left side of the back surface of the frame 2. The telescopic end of the electric push rod 26 is fixedly connected to a connecting rod 27. The other end of the connecting rod 27 passes through the square hole 25 and is rotatably connected to the first driven wheel 13.

[0037] By starting the electric push rod 26, the connecting rod 27 can drive the first driven wheel 13 to move left or right, so that not only the tightness of the sand belt body 15 can be adjusted, but also it is convenient for the staff to disassemble and replace the sand belt body 15.

[0038] Furthermore, the gasket 10 has a square appearance, and the length of the gasket 10 is equal to the length of the clamping plate 9.

[0039] The gasket 10 can be made of rubber. Since rubber has a soft property, it can provide good protection to the workpiece when clamping the workpiece.

[0040] Furthermore, the outer surface of the round block 22 is slidably connected to the inner wall of the through hole 18, and the diameter dimension of the round block 22 is the same as the width dimension of the through hole 18.

[0041] Furthermore, the number of the second driven wheels 14 is two, and the two second driven wheels 14 are symmetrically arranged.

[0042] Working principle: First, the operator places the workpiece on the top of the slide plate 5, and then starts the brake motor 7 to make the lead screw 8 rotate, so that the clamping plate 9 and the gasket 10 can move. With the cooperation of the fixed block 6, the workpiece is clamped and fixed. Then the operator starts the drive motor 11, which can make the abrasive belt body 15 rotate at a high speed. Subsequently, the cylinder 23 can be started to make the square plate 4 move upward under the guiding action of the guide rod 24, so that the clamped and fixed workpiece can approach and contact the abrasive belt body 15, thus realizing the grinding of the workpiece. During grinding, if the width of the workpiece is wider than the width of the abrasive belt body 15, the operator can start the servo motor 19, so that the rotating shaft 20 can drive the disc 21 and the round block 22 to rotate. Due to the rotation of the round block 22, the inner wall of the through hole 18 will be squeezed, so that the square rod 17 can drive the slide plate 5 to reciprocate along the surface of the guide rail 16, and then the top surface of the workpiece can be evenly polished by the abrasive belt body 15, so that the polishing process of workpieces wider than the width of the abrasive belt body 15 can be applicable.

[0043] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
